A Slack alternative for communities

Slack is excellent at work. Plenty of communities run on it anyway, and then hit the edges: work identities, history that fades on the free plan, and voice that has to be started as a call.

Why communities outgrow Slack

It is not work: A community needs Discover, invite links anyone can share, roles people pick for themselves, events with RSVPs and a Home that says what the place is for.
Voice should be a place: In Sazlo a voice room is always there. You see who is in it and click to join, no call to start. Voice and video.
History is the community: Old answers, old jokes and old decisions are why people stay. Sazlo keeps them searchable with from:, in:, has:, before: and after:.
Moderation built for strangers: Timeouts, bans that end on their own, auto filters, membership screening, reports that never name who reported, and an audit log.

When Slack is the better pick

If you are a company that needs single sign-on, compliance exports and the deepest catalog of work apps, Slack is built for that. Sazlo imports the public channels of a Slack export; private channels and direct messages stay behind.

Questions

Can I use Sazlo for a team at work?

Yes. Studios and small teams use spaces with private rooms, roles, voice, threads, scheduled messages and a GitHub integration. See Sazlo for studios.

Can I import a Slack workspace?

Yes. Upload a Slack export and Sazlo brings public channels, threads, reactions, edits, canvases as docs and lists as tasks. Private channels and direct messages are always skipped.
